2 Claims.

This invention relates to a metal sash surround adapted to receive a window sash and frame and further adapted to provide a metal trim about a window opening. More particularly the invention relates to a sheet metal form of surround including integral flanges providing a border for a' finishing material, such as stucco, around the window and including novel means of securing separable portions of the surround to one another to form an integral structure.

The instant invention contemplates the provision of a sheet metal window framing structure which is capable of being fabricated in unitary strips comprising top, bottom and sides respectively which are thereby knocked down for shipment and which may be assembled prior to forwarding to a job.

It is among the objects of this invention to provide a new and improved sash surround having a neat and finished appearance and which is capable of ready mass production on an economical basis.

It is also among the objects of this invention to provide in a metal sash surround of the desired character described, new and improved knock down and assembled features.

- a new and improved adjustable interlocking feature.resulting in a rigid and economical construction capable of assembly for use by means of. a few simple tools, as a pair of pliers. H

. .It is ,likewise among the objects of this invention to provide new and improved corrosion resisting construction with improved features of imperviousness to weather, seepage, moisture and the like; and to provide improved features of inter-relation and correlation of the surround with a window and its finish and a building and its finishing material.

. Also within the contemplation of this invention is the provision of improvement over prior art structure and methods heretofore contemplated for generally similar purposes.

With these and other objects in view, the invention consists of the construction, arrangement and combination of the various parts of the device whereby the objects contemplated are attained, as hereinafter set forth, pointed out in the appended claims, and illustrated in the accompanying drawings.

In the drawings- Figure 1 is a front view of a window including a surround embodying this invention;

Figure 2 is a plan sectional view taken as on' a line 2-2 of Figure 1;

Figure 3 is a vertical sectional view taken as on a line 33 of Figure 1;

Figure 4 is a fragmentary perspective view of a surround exemplifying this invention;

Figure 5 is a detailed sectional view on a line 55 of Figure 4;

Figure 6 is a fragmentary exploded sectional view of said surround;

Figure 7 is a fragmentary perspective view from the back side of a surround exemplifying the invention.

Referring more particularly to the drawings, there is illustrated by way of example but'not of limitation windows as 20 and 2| set within a sash 22 mounted as upon a frame 23 by means of hinges 24 or the like. i

The frame 23 is ordinarily and preferably formed of metal as is the sash 2'2, the-former being securedas to the finish trim 25 or framing 26 of the main building structure as by-means of screws 21. The finish trim 25 is ordinarily lumber and the wood framing 26 ordinarily comprises 2 x 4s framing the window opening.

The surround designated generally at 30 comprises preferably interchangeable sides 3| "and 32, a top 33, and a bottom 34.

The sides 31 and 32, as may'be most clearly seen from the drawing of side 3| in Figures! and 6, and 7-, each comprise elongate members including an attaching flange 36 formed as along a bend line 31 to constitute one wall of a channel 36, the other-wall'39 of which is formed with "a double-folded edge 46 preferably parallel to the plane of the attaching flange 36.

The doubled trimming flange 39 is folded as at M, the outer wall 42 thereof extending rearwardly as at #3 beyond the securing flange 36'. As by means of a fold line 44, an offset 45 is formed and a further fold as at 46' provides a terminal securing flange 41.

The innermost wall 50 'of the channel 38- is undercut at its rearward extension and the offset portion 45 is correspondingly shortened at the upper and lower ends of each side 30 and3| to form longitudinally projecting tongues 5| and 52 preferably lying in the plane of the channel 38.- Said undercut also forms terminal extensions 53 and 54 at the'top and bottom respectively of each attaching flange36.

Top member 33 is formed with an upwardly directed attaching flange forming one wall of a channel 6| whose other wall is formed by-a doubled trimming flange 62 having a forward edge 63 at the top thereof. f

The other wall 64 of the channel 38 in'additaken as tion to forming a bottom thereof extends rearwardly as at 65 of the attaching flange SI} for a distance corresponding to the rearward extension 43 of the inner wall 42 of the side members 3| and 32 The bottom wall 64 is turned down as at 66 to provide a securing flange 61 lying rearwardly but in a plane parallel to the attaching flange 60.

A preferably rectangular opening 68 is formed through the bottom of the channel Bl at a position spaced rearwardly of the trimming flangev 62, forwardly of the attaching flange 60, and inwardly from the ends Ill and H of the topmember 33. The openings 68 are adapted to accommodate the tongues 5| guided by outwardly extending ends 13 on the attaching flange 50.

A bottom member 34 is provided with an attaching flange 15 having outwardly projecting ends 16. A sill forming flange '18 has a portion 19 extending outwardly at approximately rightanglesuto the attaching flange 15' and includes a downwardly directed lip 83 having a folded edge Bl by virtue of which the. lip and the portion 19 are double, being formed with an upper wall 82 and lower wall 83. The upper wall 82 has an inward extension 84 relative to. the attaching flange '15 and then forms an offset 85, and a terminal securing flange 86, the latter being formed as with a cut-out 81 to accommodate the off-set and terminal securing flange 41 of the side members 3| and 32 at either end thereof.

-A cut-out 90 provides an insertion space for the downwardly extending terminal extensions 54 forwardly of the lateral extesion 16 at either end of the bottom member.

Similarly, openings 9| are formed in the sill portion 19 at either end thereof to accommodate the downwardly extending tongues 52 of the side members 3| and 32, respectively.

Each of the side members 3| and 32, the top member 33 and the bottom member 34 is separately formed. They may be secured together to form a surround by insertion of the upwardly extending tongues 5| and the openings 86, the upwardly extending terminal 53 of each side member being then adapted to provide or underlie the lateral extension 73 of the topmember and the downwardly extending flange 51 of the top member being accommodated in front of and thus; overlying the ofiset 45 of the side members.

In a similar manner; the downwardly extending tongues 52 are inserted through the opening 9!. The downwardly extending portion 54 of either side member are adapted to overlie the lateral extensions 16 by virtue of the cut-out 90.

It may be observed that the tongues 51 and 52 are of substantial length. Accordingly, when they are inserted through the openings 68 and. 9| respectively they may be doubled over the ends of the top and bottom members as shown most clearly in Figures 4 and 5'.

The inner wall 59 of the side channel 38 is adapted to abut at its upper end 95 against the lowermost wall 64 of the topchannel 6!. When the tongue is folded around the outer edges 10, for example, of the top member and then pinched therearo-und as indicated at 91 and 98, as they may readily be by means of a pair of pliers, a flrm securement of the members to one another is made.

In view of the length of the tongues 51 and 52 and due to their flexibility, where necessary to make an accurate fit, the upper and lower members may be relatively separated by utilization of only the upper and lower portions of the tongues 4 in which case the inner wall 50 will not abut against the bottom of the tongue 6 I, for example, at the top. Similar utilization of the extreme top and bottom ends of the tongues permit their outward lateral bending whereby the side memhere may be spaced relatively further from one another than the distances between the openings 68 or 9| on the top and bottom members respectively.

The amount of vertical as well as lateral adjustment of the members relative to one another is thus determined by the length of the tongues 5! and 52, and although the members are constructed to meet specific measurement they may be expanded if need be beyond such measurement.

The flange 8? of the bottom member and the corresponding flanges 41 of the side members may be formed with nail or screw holes as .desired or they may be secured to the frame of the window as shown most clearly in Figure l and also at the sides and bottom respectively in Figures 2 and 3.

The terminal flange 61 of the top member may be similarly secured in any desired manner to the top of the frame 23. Because of the offset 45 of the side members or 85 of the bottom member, the outer surface I08 of the frame may lie substantially in the plane of the respective securing flanges 3B and 65 while still leaving room the customary caulking compound Ill].

The attaching flanges 3B, 60 and 15 may be provided as with nail holes I02 as desired whereby they may be secured to the wood frame 26 or the like forming the rough frame for the window opening.

Stucco or any other desired wall finish I03 applied to the outer surface or the building structure is accommodated and held in place adjacent the window opening by the channel 38 in. the side members and at 6! in the top member.

Building finishes, whether cementitious or not,-

may be laid. flush with the trimming flanges 39 and 52 as shown at I04, Figure 2. Other buildr ing finishes such as lumber may likewise be accommodated entirely within such channel as indicated by the, phantom outline I05 in Figure 2.

A downwardly extending lip or rain drip overlies the upper margin H15 of the finish I03 as indicated in Figure 3, thus protecting the same from the weather and other erosional influences.

The above construction has the advantage, among other things, of simple assembly, adjustability for variant opening dimensions, rigidity and economy of construction, elimination of spot welding and other conventional means of surround manufacture and assembly. In view of the seamless construction thus provided moisture is excluded from penetrating the surround particularly in the area of the fold 3! of the side, 66 of the top and I58 of the bottom member. Moreover, the doubled edges of 40 of the side members and 63 and SI of the bottom members avoid raw edges, further resisting corrosion occasioned by raw edges, thereby adding to the life of the product and avoiding staining, discloration and the like incident to prior art surrounds.

The above construction has been found particularly adapted for fabrication in sheet metal. The construction, however, lends itself to other methods of production including molding and ex .trusion, particularly metal extrusion. In either case the channel construction and flanges may be rounded or made relatively right lined within the skill of the artisan.

Although the invention has been herein shown and described in what is conceived to be the most practical and preferred method and embodiment, it is recognized that departures may be made therefrom within the scope of the invention, which is not to be limited to the details disclosed herein but is to be accorded the full scope of the claims so as to embrace any and all equivalent structures and methods.

The invention having been herein described, what we claim as new and desire to secure by Letters Patent is:
